ROTARY CHURN.

SPECIFICATION forming part Of Letters Patent NO. 413,978, dated October29, 1889.

Application filed April 1, 1889. Serial No. 305,642. (No model.)

To all whom it may concern.-

Be it known that I, HENRY F. STOETERAU, a citizen of the United States,residing at Davenport, in the county of Scott and State of Iowa, haveinvented a new and useful Rotary Churn, of which the followingisaspecification.

My invention relates to rotary churns; and it consists in certain novelconstructions and arrangements of parts, fully described hereinafter,and specifically pointed out in the claim.

Figure 1 is a front view of the churn and frame. Fig. 2 is a side viewof the same. Fig. 3 is a view of a vertical section of the churn. Fig.dis a plan View of the upper section of the dasher, the lower transversebar removed. Fig. 5 is a plan view of the top of the miter-pinion andradially-extended supports for the churn. Fig. 6 is a side view of themiter-pinion and its vertical shaft, together with the bracket; and Fig.7 is a crosssection of the socket for holding the horizontal bar orlower section of churn-dasher.

Similar letters and figures refer to similar parts throughout theseveral views.

The frame consists of four posts, the two front or taller posts beingdesignated by the letter A, and the two rear or shorter posts beingdesignated by the letter B. Suitable cross-bars G are framed between theposts to construct the frame in a substantial manner. Centrally fromside to side are framed the cross supporting-bars D D, one above theother. Standards E are attached to opposite sides of the'frame,extending vertically above the frame. I hinge a shelfF to the rear postsB and sustain it in an operative position by the hook and eye f.

G is a cross-bar hinged to one end of the standard E, the other endslotted to permit the end of the other standard to enter such slot,where it is secured by a pin. Such crossbar is also centrally providedwith an aperture, and on its upper surface, next to said aperture, is abutton 9, secured by a pin.

8 is a bracket or hanger provided with the horizontal arms 9, verticallyperforated through inward vertically-extending collars 10, and 11 is ahorizontal inward-projecting collar, with a horizontal longitudinalperforation extending through such collar and also continued through thebracket.

12 is a miter-pinion having its teeth on its lower face attached to avertical shaft 13, provided with a shoulder 14 next to said pinion. Fourradial brackets (designated by the figures 15) are attached to the topsurface of said pinion, forming a seat for the four radial churn-supportbars 16. The horizontal bars 9 of said bracket 8 are seated centrally inthe frame on the bars D D, and the bracket secured thereto by screws orbolts. A journal-box 17 is attached to the upper surface of one of thecross-bars O, in line with the perforation through collar 11. The bars DD are perforated to receive the collars 10 and permit the vertical shaft13 of the pinion to pass through the same. A shaft 18 has near its innerend attached to it a miter gearwheel 19, with teeth on its inner face,such shaft on the inner side of said wheel having its bearing in theperforation through collar 11, its outer bearing being in journal-box17, and outside thereof having attached a crank 20. Miter gear-wheel 19meshes and engages with pinion 12. The link 21 is at one end attached bya pin to the end of crank 20, and its opposite end attached to the lowerend of the handle 22, also by a pin. Said handle is attached to thefront surface of one of the posts E of the frame also by a pin. Movingthe handle forward and backward causes, through the mechanism described,the radial churn-support bars 16 to rotate. The handle 22 may be movedto a horizontal position on a line with cross-bar O, and the end of suchhandle and crank connected by the link, and the machine operated bymoving the handle up and down, commonly called a pump motion.

One of the important features of my in= vention is the ease with whichit may be operated.

The churn 23 is cylindrical and constructed of staves of wood hooped,having a bottom 24: and a chine 25. The top of the churn, on its innersurface, is beveled, as at 26, to accom modate and support the cover 27,which is made in two halves and centrally cut out to leave a small holeor perforation 28. Upon the inner bottom surface of the churn areatrounded at their outer end and side surface,

as at 36, and have pins 37 at their inner sides extending from the endsof the wings, which enter the perforations at the vertex of said angles.Similar pins 37 are at the opposite ends of said wings, which enterperforations in the upper surface of transverse bar 31,

A vertical shaft 38 is attached in the upper surface of transverse bar30, which is provided with the button-groove 39. The lower section ofthe dasher is a transverse bar 40, centrally attached to the lowersurface of transverse bar 31 by a pin, so it may rotate.

When the dasher is inserted within the interior of the churn, the endsof transverse bar 40 are seated in the sockets 29 and the shaft 38protrudes upward through the perforation 28 of the churn-cover 27. Eachof the radial churn-support bars 16 are notched near their outer ends,as at 41, into which notches the chine 25 of the churn body snugly-fits,thus holding and supporting the same. The cross-bar G is thrown over tothe opposite standard, the vertical shaft 38 extending through theperforation therein, and the button gis turned so as to enter the groove39 in said shaft, and the cross-bar is secured to the standard by thepin.

In one side of the churn, near the bottom, is inserted a small tube 42,for the purpose of withdrawing the fluid from the churn into a pailsupported on the shelf F, and which tube may be closed with a cork.

In operation the lower section of the dasher 40 rotates with the churn,while the upper section remains stationary. The churn should be rotatedin the direction which causes the fluid to move against the innersurface of the Wings 35, which throws the rounded surface of the wingsagainst the interior surface of the side of the tub, compelling suchfluid to pass between the two wings and against the posts 33.

A dasher constructed as described is removable from the churn, leavingthe bottom and sides of the churn free to be cleaned, and the twosections of the dasher allowing of sepa ration may thus be moreeffectually cleaned.

I do not claim, broadly, adasher which may be held stationary within theinterior of a r'otating churn, nor mechanism for rotating such churn,nor a transverse bar across the bottom of the churn rotating therewith;but

hat I do claim as new, and desire to secure by Letters Patent, is

In a rotary churn and frame,'witl1 mechanism for rotating thechurn-body, the combination of socket-pieces attached to the innerbottom surface of the churn-body, the transverse bar 40, adapted to beheld in said socket-pieces, the horizontal transverse bar 31, centrallypivoted to the upper surface of bar 40, the horizontal transverse bar30,

having angled slots, located within the interior of the churn-body andabove bar 31, the vertical posts 33, connecting bars 30 and 31, thevertical wings 35, pivotally connected to said bars 30 and 31, thecentral vertical shaft 38, attached to the bar 30 and extending abovethe churn-body, the cross-bar G of the frame horizontally above thechurn-cover, and means for attaching said shaft to said cross-bar,substantially as described.
